Question

jose needs 6.2 lb of organic blueberries to make smoothies. organic blueberries are on sale for $2.85 per pound. jose estimates that he will need $12 to buy the 6.2 lb of blueberries. what is joses error? jose incorrectly rounded $2.85 down to $2. the estimate should be $18. jose incorrectly rounded 6.2 up to 7. jose incorrectly multiplied 2 and 7. the estimate should be $14. jose did not make an error. his estimate of $12 is correct.

Explanation:

Step1: Round the price per - pound

Round $2.85$ to the nearest whole number. Since $2.85$ is closer to $3$ than $2$, we round it up to $3$.

Step2: Round the weight

Round $6.2$ to the nearest whole number. $6.2$ is closer to $6$ than $7$, we round it down to $6$.

Step3: Calculate the estimated cost

The estimated cost is the product of the rounded - price and the rounded - weight, so $3\times6 = 18$. Jose incorrectly rounded $2.85$ down to $2$.

Answer:

Jose incorrectly rounded $2.85$ down to $2$. The estimate should be $18$.
